🚨 PSA for all of you updating your apps for iOS 26:
When you build using Xcode 26, the large navigation title gets broken (no left padding) when running on iOS 18.
🔗 Link to a fix below.

Anyone hit problems enabling approachable concurrency (or flags in its grouping) aside from the migration step required for NonisolatedNonsendingByDefault? Not talking about default isolation here.

I haven't encountered any anywhere and I'm curious. Seems like it is going quite smooth so far.

Agreed, it does feel clumsy

thanks, I’ll take a look. I’ve used that approach in the past (see useyourloaf.com/blog/scenest...) not sure why I’m not doing it here

When Observable replaced ObservableObject in iOS 17 it was missing a way to stream changes. That was fixed in iOS 26 (swift 6.2). #iosdev #swiftui useyourloaf.com/blog/swift-o...

Swift 6.2 introduces a new Observations type to stream state changes from an Observable type.

that’s a good point, not sure it’s possible but would be nice to have as a fallback

Yes, I had the same problem, the WWDC video skips over what you’re supposed to do. In theory, the icon is backwards compatible so you only get the glass effect on iOS 26. In practice, seems there are some rendering issues on older versions.

I found a workaround to the problem with Icon Composer not working for alternate app icons. Manually adding keys to the target's Info.plist seems to fix it for now. Seems to need separate keys for the ~ipad variant. Hopefully Apple fixes this soon. #Xcode useyourloaf.com/blog/adding-...

Here's what worked for me in the end after comparing to what Xcode generates for app icons in the asset catalog. The iPad variant seems to be necessary for it to work there. Hopefully Apple fixes Xcode in a future beta,

Info.plist with CFBundleIcons~iPad and CFBundleIcons dictionaries listing CFBundleAlternateIcons

Keith Harrison @useyourloaf.com · Jun 25

Thanks. One difference I can see is that I don't have the CFBundleAlternateIcons key listed in the Info.plist file. (I'm also using a SwiftUI app life-cycle but not sure that's relevant). Will play some more. Thanks again!

Keith Harrison @useyourloaf.com · Jun 24

Interesting, will have another look. To be clear you didn’t have to add the icons to the asset catalog?

My notes on the surprising (to me) scope of SwiftUI keyboard shortcuts #SwiftUI #iOSDev useyourloaf.com/blog/swiftui...

SwiftUI Keyboard Shortcut Scope

A SwiftUI keyboard shortcut remains active as long as the control it's attached to is still in the view hierarchy, even when not onscreen.

Is there no way to set the accessibility language for a SwiftUI view? UIKit has the accessibility language property but there’s no equivalent in SwiftUI. I’ve seen people using AttributedString with the .accessibilitySpeechLanguage attribute but I can’t get it to work. #SwiftUI #iOSDev

Yes, I've seen that. Very frustrating. Hope Apple fixes that soon. I'll add a note to the post. Thanks.
